Recently attorneys for Facebook, Twitter, and Google were called before the Senate Judiciary Committee to answer for the role their companies played in amplifying the messages from Russian actors that influenced the 2016 American Presidential election. The details surrounding this issue have profound consequences for the nation politically, geopolitically, culturally, financially, legally, and technologically. Vidya is a technology company, so let’s focus only on that last one and leave it to others to address the rest.
The most memorable part of the hearing was a heated exchange between Senator Al Franken (D-Minnesota) and Facebook General Counsel Colin Stretch:
Senator Franken, who has not lost the sarcasm and timing that made him a great satirist, clearly was annoyed with Mr. Stretch for his refusal to accept the proposition that payment in foreign currency for ads pertaining to American elections is a clear indicator of something nefarious. The reason? As Mr. Stretch put it:
The currency signal...it's very easy to manipulate.....The reason I am hesitating on foreign currency is that it is relatively easy for bad actors to switch currencies. So it's a signal, but it's not enough.
It’s interesting that Mr. Stretch (and his fellow witnesses) would use data science jargon like signal before the committee. A signal is a dimension of your data set that offers predictive value for the outcome you’re tracking. Everything else is noise. For example, if you are trying to predict who will win a game, the records of the teams is a reasonable signal; the lengths of the first names of the best players on each team, not so much. At a high level, data science is largely about separating signals from noise and then measuring the degrees to which each signal influences the outcome. So according to Mr. Stretch, while the form of currency used to pay for an ad on Facebook is a signal, it is only definitive in combination with other signals and therefore shouldn’t factor alone in any decisions by Facebook.
That statement is true. It also avoids Senator Franken’s question while leaving Facebook with wiggle room. This is an attorney who earns every penny.
Let’s cut through the obfuscation because the core of this is really quite simple. It’s true that bad actors can hide intent by choosing the appropriate currency for the country where they wish to advertise. As Mr. Stretch suggests, merely paying in dollars to advertise in an American election doesn’t reveal much about the advertiser.
But what about paying in rubles or won to advertise in an American election? Senator Franken thinks rejecting those ads should be a no-brainer. In fact, we could generalize his thinking beyond the United States with an algorithm expressed in trivial Scala-ish pseudocode:
if (ad currency == country currency) analyzeFurther() else NOPE!
As it turns out, you don’t even need data science to have rejected many ads on social media from the 2016 campaign season–just a raw comparison of data elements.
That may have been the source of Senator Franken’s frustration. Of course if the condition is
true (e.g. an
American campaign ad is paid for with American currency), you need
real analytics to refine a model that predicts whether the ad is funded by a bad actor, but can’t we at least reject
outright all the obvious bad actors who don’t even try to hide their intentions and can be identified with no analysis at all?
Mr. Stretch managed to dodge, duck, dip, dive, and dodge long enough to avoid that question as Senator Franken ran out of time. No other senator followed up. It was a clever tactic by Mr. Stretch to use a particular scenario where currency is an inconclusive signal as cover for all cases and run out the clock. As a result Facebook and its brethren escaped the hearing without any commitment to rejecting political ads plainly funded by foreign currencies. None of these companies want to tell their shareholders they’re abandoning significant revenue, and they don’t want to say anything that could open them up to legal action. But as I said earlier, let’s leave matters of finance and law to others.
Technology continues to move faster than the speed of law as its grip on every aspect of our lives grows tighter, but it remains a black box to the very people who need to understand it. Senator Franken made a valiant effort to hold social media accountable for their actions during the 2016 elections, but until politics and law make the effort to discern signals from the noise produced by large tech companies, their unchecked influence will have continuously greater repercussions for all of us.
